IM PROVEIVIENT IN COTTON-PRESSES..

' Specification forming partzoi: Letters Patent No. 29.290, dated July 24, 1860.

.To all whom it may concern.-

Be it known that I, HENRY MASON, of Lancaster, in the county of Worcester and State of Massachusetts, have invented a certain new and useful Improvement in the Press for Pressing. Cotton and other Substances; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being hadfto the accompanying drawings, making part of this specification, in which-4 Figure 1 is a plan; Fig. 2, a side elevation, and Fig, 3 an endelevation.

The same letters indicate like parts in all the gures.

The objectV of my invention is to make a press for pressing cotton which, by ldirect coggearing operated bya constant power applied to a rotating shaft, shall work the platen with a gradually-increasing power proportioned to the gradually-increasing resistance as the cotton or other likearticle is being compressed; and to this end my said invention consists in combining the platen ofthe press,when operated by a cogged pinion and cogged rack or the equivalent of these,with thev driving-shaft, by whatever power the said shaft may be Op'- erated, by means -ot' two increasing and decreasing gears-one on the driving-shaft or the equivalent thereof, and the other on the shaft which communicates motion, directly Or indirectly, to the platen-the said increasing and decreasing gears being .so formed that the pitch-line of the cogs of the one on the driving-shaft, or the equivalent thereof, gradually approaches the axis, and the pitch-line of the other gradually recedes from the axis, the one gradually increasing in leverage over the other.

In the accompanying drawings, c represents the movable platen of a eotton-press,which is to Operate against a fixed platen in the usual manner, and which therefore does not require to be represented. The under side of this platen-shaft.

-nate an increasing-gear,77 j

to and is to impart motion to the platen-shaft' en-shaft e is another shaft, f,which I terln the driving-shaft, although the driving-power, instead of being -applied directly to this shaft, may be applied to another shaft, g, which vcarries a pinion, h, that engages a cog-wheel, i, on the driving-shaftf.

On the platen-shafte there is whatI denomi- It is attached e. Its periphery is formed with cogs, and from the rst cog at j to the last at j each cog is in succession of a greater radius, the increase of radius being regular, and On the driving-shaft f there is what I term a decreasing-gear, k, which-is precisely the reverse of lthe increasing-gear j on the platenshaft, so that the iirstcog, k', on the decreasinggear is of the greatest radius, and each in suceessionwqf less radius to the last, k2, which power to correspond withthe gradually-increasing resistance of the article that is being pressed-such as abale of cotton-which result I am enabled to attain by a simple gear.

The ratio of increase may be varied at the discretion of the constructer, who can in this way suit the increase to the natureof the artiele intended to be pressed. 'The proportions given in the accompanying drawings I deem the best forprcssing and baling cotton.

What I claim as my invention, and desire to l secure by Letters Patent, is-

Combining the platen-shaft or any equivalentshaft with the driving-shaft or any equivalent shaft by means of increasing and decreasing gears, substantially as and for the purpose specified.
